Description

Technical Field

[0001] The present invention belongs to the technical field of high-temperature work clothes, and particularly relates to an individual cooling and protection system that takes into account maritime rescue and escape. Background Art

[0002] In the southern waters of China, the weather is hot and humid. During wartime, in order to protect the safety of the internal crew members, all intake and exhaust channels in the cabins and amphibious armored vehicles need to be closed to form a sealed space. In the sealed space, the air circulation is limited, and there is almost no material exchange between the inside and the outside environment, resulting in a series of problems regarding personnel safety. On the one hand, the heat transfer between the sealed space and the external environment depends on heat conduction and heat convection in the form of: internal environment air → wall surface → external environment air, with low heat dissipation efficiency. Moreover, the heat loads of personnel and equipment are large, and the external solar radiation intensity is high, causing the temperature in the sealed space to reach over 50 °C, posing a great threat to the lives of personnel. On the other hand, the air humidity in coastal areas is high. The evaporation of the crew's sweat in the sealed space causes the humidity inside the sealed space to approach saturation, which not only easily corrodes the on-vehicle oxygen generation equipment but also makes it difficult for the crew's sweat to evaporate, causing the core body temperature of the human body to rapidly rise above the threshold and resulting in heat injury. Some sealed spaces do not have air-conditioning equipment, and the temperature and humidity in the sealed space are very high during training, causing great heat injury to the crew, leading to problems such as heatstroke and heatstroke. Moreover, some sealed spaces equipped with air conditioners often malfunction due to factors such as bumps, seawater corrosion, and unstable on-vehicle power supply voltage, with high maintenance costs and short cycles. The method of using ice cubes and fans carried by the crew to cool down has an unsatisfactory effect and is difficult to effectively guarantee combat and training lasting for more than three hours. Therefore, how to effectively supply cold in a high-temperature and high-humidity sealed space without a power source is crucial for ensuring the safety of the crew.

[0003] In the field of ensuring the safety of high-temperature workers, people usually use fan clothes, phase change heat storage clothes, and ice-cold fans for cooling. Fan clothes use fans to increase the evaporation rate of sweat on the human body surface, but it is difficult to effectively cool down in a high-temperature and high-humidity sealed space. Phase change heat storage clothes embed phase change heat storage materials inside the clothes, and personnel need to work while wearing the phase change heat storage clothes. In order to prevent affecting the work efficiency of personnel, the mass of the phase change materials carried by personnel is limited. Therefore, the endurance time of the phase change cooling clothes is relatively short. The ice-cold fan combines ice cubes and a fan. The air entering the fan exchanges heat with the ice cubes and then blows out. Due to the small heat exchange area between the ice cubes and the air, low heat exchange efficiency, and high relative humidity, its cooling effect is poor and the cold energy loss is large. Moreover, the fan requires power supply, resulting in low environmental adaptability and low cold storage density. If the heat dissipated by the human body can be transported against the temperature gradient to the surrounding environment, it is possible to more effectively and stably ensure the safety of personnel in a high-temperature environment. Summary of the Invention
